SAW.

SPECIFICATION forming part of Letters Patent No. 7 35,586, dated August4, 1903.

Application filed October 6, 1902.

To all whom it may concern:

Be it known that I, ZEPHIRE RABIE, a citizen of the United States,residing at Two Harbors, in the county of Lake and State of Minnesota,have invented certain new and useful Improvements in Saws; and I dodeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

My invention relates to improvements in saws; and its object is toprovide a device of this character which is simple in-construction,comparatively inexpensive of production, durable in use, and veryefficientin operation.

With these objects in view the invention consists in certain features ofconstruction and combination of parts, which will be hereinafter fullyset forth.

Figure 1 is a side elevation of a reciprocating crosscut-saw with itsteeth arranged ac cording to my invention. Fig. 2'is a crosssectionthrough the same. Fig. 3 is an enlarged side elevation of the centralportion of the saw, showing more clearly the shape of the teeth.

In the drawings, A denotes the saw-plate with a curved working edge, Bthe-cuttingteeth arranged in pairs, and O the drag-teeth between them.The cutting-teeth B upon each side of the center line 000: have theirrespective cutting edges reversely disposed and inclined outwardlytoward the respective ends of the saw and obliquely to the axis of thesaw to form planes inclined at such an angle as to direct the sawdustupwardly thereon from their points toward their bases to keep theirpoints clear. The drag-teeth O are also inclined or pitched away fromthe center line a: 00 and are swaged to enable them to draw the sawdustfrom the kerf or out. As will be noted by the dotted line y y, thecutting edge of the saw is slightly curved or inclined away from thecenter line a", a2. In practice I prefer to make the saws four feet ormore in length and have the top or back a very thin. As shown in Fig. 2,the plate Serial No. 126,198. No model.)

A is tapered from the teeth to the top or back edge a. By thisconstruction it will be seen that the saw will not bind in the kerf whenin use.

From the foregoing description, taken in connection with theaccompanying drawings, it is thought that the construction, mode ofoperation, and advantage of my improved saw will be readily apparentwithout requiring a more extended explanation.

Various changes in the form, proportion, and the minor details ofconstruction may be resorted to without departing from the principle orsacrificing any of the advantages of this invention.

Having thus described the invention, what I claim is 1. Asaw providedwith cutting-teeth which have their respective cutting edges reverselydisposed on opposite sides of the center of the saw and inclinedoutwardly toward the respective ends of the saw and obliquely to theaxis thereof to form planes inclined at such an angle as to direct thesawdust upwardly thereon from their points toward their bases, to keeptheir points clear, substantially as described.

2. A saw having its cutting edge provided with triangular cutting-teethand drag-teeth, the cutting-teeth having their cutting edges reverselydisposed on opposite sides of the center of the saw and inclinedoutwardly toward the respective ends of the saw and 0bliquely to theaxis thereof, to form planes inclined at such an angle as to direct thesawdust upwardly thereon from their points toward their bases, to keeptheir points clear, and the drag=-teeth being disposed each inalternation with a plurality of cutting-teeth, substantially asdescribed.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses. p
